JUST ONE. Insulating skeleton or insulation material
The skeleton generally adopts the injection molding process, and the quality on the mold, the control in the injection molding process, and the cleanliness of the cheap particles will all result in its defects. The defects on the framework or insulating products are as follows:
(1) The actual skeleton is short associated with materials;
(2) Damaged;
(3) Maxed by the short-circuit engagement ring;
(4) The framework contains impurities;
(5) There are dirt such as greasy dirt on the surface with the framework;
(6) The insulation sheet is pierced.
2. Hanging the wire during the winding process of your wire package
Shorten while in winding. Because the stator as well as the frame do not healthy together, the winding needle of the winding machine probably are not adjusted to be completely in the upper part of the frame, and there can be a certain arc when winding the needle as well as wire during winding, which might cause the enameled wire never to be embedded in your designed track The insert package, the wire presents itself, that is, the enameled wire just isn't wound on the cheap frame, and there are loops or several loops around the vertical offset or transverse groove outlet, or slip into your gap between the stack and also the silicon steel stator. Within the stator, various faults occur normally, and other undesirable phenomena contain:
(1) The first cycle of wire hanging in the beginning of winding;
(2) The skeleton has burrs as well as the wire is stuck and is not embedded;
(3) Waste wires fit in the wire package during the production process of workforce;
(4) The wire package deal is unilaterally skewed or fully out.
Third, the wire hanging due to the wiring process
(1) The connectors somewhere between the wire packages usually are not arranged and stuffed in to the frame after welding, and the wire ends are too towards the stator and the stop cover;
(2) After the past round of enameled wire is loose, it falls out of your frame and is possibly not found. Pull it directly from your frame and come with the stator;
(3) Floating wire for the lead wire;
(4) The actual thermal protector squeezes away the wire. The general structure should be to wrap the enameled wire throughout the copper core of that thermal protector and cover it that has a sleeve for insulation security, but if it will be misplaced, it will result in breakdown.
